I SPECIFICATION forming part of Letters Patent No. 731,733, dated J une23, 1903.

` Application filed February 27,1908. Serial No. 145,31'8. (No model.)

To @ZZ whom, it may concern:

Be it known that I, JOHN MCE. AMES, a citizen ofb the United States,residing at New York city, county and State of New York, have inventedacertain new and useful Im- Iprovement in Underframing for Railway- Cars,of which the following is a full, clear, and exact description, such aswillenable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, formingpart of this specification, in which- `Figure lis a plan view of one endof an` underframe containing my invention.

Fig. `2 is a longitudinal sectional view taken on line 2 2 of Fig. 1.Fig. 3 is a transverse section of Fig. 1, taken on line 3 3; and Fig. 4is` a detail view of a modified rform of construction hereinafterreferred to.

This invention relates to new and useful improvements in underframingfor railwaycars; and it consists in certain features of novelty 'in thedetail construction and arrangement of parts thereof, all as hereinaftermore fully described ,and particularly pointed out in the claims.

The object of the invention is to provide a -`simple and economicalconnection between the center sills employed in my improved underframeand the draft-sills thereof which e `will enable the parts to be easilyassembled and readily repaired in case of partial destruction.l

Referring to the drawings, 1 is the-end sill. 2 represents the .sidesills. 3 representsthe center sills.

`4 represents the draft-sills.

. 5 is an intermediate connecting member interposed between the webs ofthe center sills 3 and the webs of the draft-sills 4 and riveted,

respectively, to said center sills and draftsills through the webportions thereof.

6 is the upper plate of a skeleton bolster extending from side sill toside sill and connected with said side sills in anyconvenient ordesirable manner. 7 is the lower member of said bolster, and 8 is afiller-block interposed between the upper and lower members of thebolster, said filler-block being provided with the usual verticalopening 9 for the kingpin. (Not shown.)

In the construction herein illustrated the `through the skeleton bolsterherein illustrated and are connected to the filler-block 8 thereof,while a portion of said center sills extends outwardly beyond saidholsters in the direction toward the end sills, whereby shortdraft-sills may be used which when connected to the center sills, asshown, form practically conti nuations thereof, though not connecteddirectly' to said center sills.

In the construction shown channel end sills are used, to which the shortdraft-sills may be connected in any convenient manner, though brackets 9are shown, through which rivets extend for the'purpose of uniting thedraft-sills andend sill, and the side sills are shown in the form ofrolled channel members with their flanges disposed inwardly.

In the modification shown in Fig. 4 the lap for a short distance only,though the plate 5 is used in such modification interposed between thewebs of the center sills and draftsills for the purpose of strengtheningthe same andextends beyond the overlapping portions at each end for ashort distance, whereby a more rigid connection between said' membersmay be provided.

I am aware that minor changes in the arrangement',construction, andcombination of the several parts of my improved underframing can be madeand substituted for those herein shown and described without-in theleast departing from the nature and principle of the invention.

Having thus` described my inventioxn'what I claim as new, and desire tosecure'by Letters Patent, ir-

1. In a metallic underframe for railwaycars, channel center sillsextending beyond the bolster at each end, rolled channel draftsillsextending from end sills to said center sills, said draft-sills havingtheir flanges diswebs of the center sills and draft-sills over- Ifoposed in :in opposite direction from the flanges of said center sills,and a Splice-plate interposed between and riveted to the webs of saidcenter sills and draft-sills; substantially as described.

2. In a metallic nnderfraine for railwaycars, rolled channel centersills extending beyond the bolster at each end, rolled channeldraft-sills extendingr from end sills to said center sills, saiddraftsills having their Hanges disposed in an opposite direction fromthe flanges of said center sills, and a. spliceplate interposed betweenand riveted to the webs of said center sills and drnftsi1ls5substantially as described.

In testimony whereof I hereunto aix my signature, in the presence of twowitnesses', this 18th day of February, 1903. y

JOHN MCE. AMES.
